The invention discloses an air duct air supply type energy-saving
cold storage. The air duct air supply type energy-saving
cold storage comprises a refrigerator, an air cooler, an air supply
plenum chamber, an air return
plenum chamber, an air supply main pipeline, an air return main pipeline, an air supply
branch pipeline, an air return
branch pipeline and at least two heat insulation boxes, wherein each heat insulation box is provided with two hole passages which are respectively connected with the air supply
branch pipeline and the air return branch pipeline; electromagnetic air valves are respectively arranged on the air supply branch pipeline and the air return branch pipeline; the air supply branch pipeline and the air return branch pipeline are respectively connected with the air supply
plenum chamber and the air return plenum chamber; the air supply plenum chamber and the air return plenum chamber are respectively connected with an outlet and an inlet of the air cooler through the air supply branch pipeline and the air return branch pipeline; the refrigerator is connected with the air cooler. The air duct air supply type energy-saving
cold storage has the advantages that only when the heat insulation boxes are connected with the air supply branch pipeline and the air return branch pipeline, the
cold air can be supplied, so that the
energy consumption of the
system is decreased; when the heat insulation boxes are handled, because the heat insulation boxes are made of heat insulation material, the
refrigeration maintaining effect is obvious, and the cold storage is especially suitable for goods requiring to maintain low-temperature state in the long-distance transportation process.
